Free Splash Pads in the Southwest Suburbs (And Which Ones Charge)

by Brian Wittman

Every splash pad list tells you where the water is. Almost none of them tell you the thing you find out at the gate: some of these are completely free, some charge your kids but not you, some charge everyone including the one year old, and non-residents pay double at most of the paid ones. Same water, very different afternoons for your wallet. Here's the full map, money first.

Which Splash Pads in the Southwest Suburbs Are Free?

The genuinely free ones as of the 2026 season: the Central Park splash pad in Manhattan, the Frankfort Square Park District Splash Park in Frankfort, and Lockport Township's two pads at Willow Walk and Hassert Park. Everything else in the immediate area charges admission, usually a few dollars per child with non-residents paying roughly double, and each district runs its own hours, season dates, and rules. All details below were checked against each park district's official published information in July 2026, but districts adjust for weather and events, so glance at their page before you load the car.

Quick picks: free and easy on a whim, Manhattan's Central Park pad runs the longest hours of any free option, with Lockport's two pads close behind. Free but plan around it, Frankfort Square runs just three hours a day. Worth a couple bucks, Yunker Farm in Mokena is the toddler pick. Making a full afternoon of it, Hibernia in New Lenox pairs the splash pad with a lake, boat rentals, and concessions.

The Free Ones

Central Park Splash Pad (Manhattan Park District), Central Park, Manhattan. Free, open 10 a.m. to 8 p.m., Memorial Day through Labor Day as weather allows, which makes it both the longest daily window and the longest season of any free pad on this list. I'll vouch for this one the way it was vouched to me: when I started asking the town's Facebook group what to do with my daughter, this was the first recommendation that came back, and the town was right.

Frankfort Square Splash Park (Frankfort Square Park District), 7540 W. Braemar Ln., Frankfort. Free, full stop, right next to the FSPD Community Center with a picnic area and pergola. The catch is the clock: it runs noon to 3 p.m. in summer, so it's a short window, and the exact season dates live in the district's summer brochure. Here's the local knowledge most parents miss: Frankfort has two different park districts, and this free pad belongs to Frankfort Square, not the Frankfort Park District that runs the paid splash park at Commissioners Park. Two Frankforts, opposite pricing.

Willow Walk and Hassert Park (Lockport Township Park District), Lockport and Crest Hill. Two free pads, no gate, no ID check, and the second longest hours on this list, running 10 a.m. to 7 p.m. daily, weather permitting in season. Willow Walk's water is motion-activated, so wave a hand at the sensor and it starts. If your crew decides at 5 p.m. that they need water, this is the one that's still on.

The Paid Ones (And What You Get for It)

Yunker Farm Splash Park (Mokena Community Park District), 10847 W. La Porte Rd., Mokena. Open daily May 27 through August 9 for 2026, then weekends only through August 30. Hours are 12 to 5:30, except Wednesdays when it runs 12:30 to 7. Admission has run $2 for residents and $4 for non-residents at the district's posted rates, charged for everyone age one and up, with residency proven by the accompanying adult's ID. First come, first served, no sessions. It's fully fenced with shaded tables, the features are scaled for little kids, and unlike most pads on this list, you can bring your own food inside, which quietly saves a family more than the gate costs. Best for toddlers on this list, and it's not close.

Hibernia Park (New Lenox Community Park District), Eagle Circle and Blarney Rd., New Lenox. Open daily May 30 through August 16 for 2026, 11 a.m. to 6 p.m., plus a bonus weekend August 22 and 23. Pricing flips the usual script: kids and anyone under 21 pay ($3 residents, $5 non-residents), while parents and guardians 21 and over get in free. Photo ID proves residency. New Lenox residents can also buy a $75 family pass good at both of the district's pads all season; for a two-kid resident family, that pays for itself around the thirteenth visit. No outside food, beverages, or coolers, but there's a concession stand, plus a stocked lake with kayak and paddle board rentals next door if the splash pad is only round one of the afternoon. One more local quirk: the pad opens free on July 4, unstaffed.

Walker Country Estates Park (New Lenox Community Park District), 299 Lenox St., New Lenox. The district's second pad, same pricing and family pass as Hibernia. It's the quieter, more neighborhood-scale option of the two.

Splash Park at Commissioners Park (Frankfort Park District), 22108 S. 80th Ave., Frankfort. The paid Frankfort option: admission has run $2 for residents and $4 for non-residents, kids under one free, with hours around 10 to 4 on weekdays and 10 to 3 on weekends and a 60-person capacity cap. Concessions on site. Verify the current season's details on the district's page before going, since capacity limits mean peak Saturdays can involve a wait.

A note on the water parks: Joliet's Splash Station and Tinley Park's White Water Canyon are full aquatic parks with slides, lifeguards, and admission prices to match. Different budget, different day, and worth it when the crew outgrows the sprayers, but they're not splash pads, so they're not ranked here.

Can You Rent a Splash Pad for a Birthday Party?

Yes, and almost nobody realizes it. Both the Mokena and New Lenox park districts rent their splash pads for private parties outside public hours, with resident and non-resident rates. For a summer birthday, a private splash pad generally runs cheaper than the indoor party venues everyone defaults to, and the entertainment is built in. Applications are on each district's site.

The Bottom Line

You don't need to spend anything to get a great water afternoon in the southwest suburbs, and when you do pay, a few dollars buys real upgrades like fencing, concessions, or toddler-scale features. The only losing move is showing up without knowing the rules: the ID checks, the no-cooler policies, the 3 p.m. shutoffs, and the temperature cutoffs (most pads shut down when it dips below the low 70s). Check the district page the morning of, bring the ID, and know whether your pad allows the cooler before you pack it.

Frequently Asked Questions

Which splash pads near New Lenox are free?

The closest genuinely free options are Manhattan's Central Park splash pad (10 a.m. to 8 p.m., Memorial Day through Labor Day), the Frankfort Square Park District Splash Park (noon to 3 p.m. in summer), and Lockport Township's pads at Willow Walk and Hassert Park (roughly 10 a.m. to 7 p.m.). New Lenox's own pads charge $3 to $5 for anyone under 21, though adults are free.

What is the best splash pad for toddlers in the southwest suburbs?

Yunker Farm in Mokena. It's fully fenced, shaded, scaled for little kids, and lets you bring your own food and drinks, which most area pads prohibit. Admission has run $2 for residents and $4 for non-residents.

Are splash pads open right now?

In season, most area pads run daily from late May through early-to-mid August, with a few extending weekends later. Nearly all of them shut off when the temperature drops below the low 70s or when lightning is in the area, so check the district's page or social feed the morning of your visit.

Can you bring food to a splash pad?

Depends on the district. Yunker Farm in Mokena allows some outside food. New Lenox prohibits outside food, beverages, and coolers at both of its pads but sells concessions. When in doubt, check the posted rules, because packing a cooler that has to go back to the car is the classic first-visit mistake.

Do non-residents pay more at splash pads?

At every paid pad on this list, yes, typically double the resident rate, and districts check the accompanying adult's photo ID to determine residency. The free pads in Frankfort Square and Lockport don't check anything.
